The life in hours of a computer processing unit (CPU) is modeled by a Weibull distribution with parameters 8 = 4 and S- 932 hours. What is the probability that the CPU fails before 518 hours? A European standard value for a low-emission window glazing uses 0.59 as the proportion of solar energy that enters a room. Suppose that the distribution of the proportion of solar energy that enters a room is a beta random variable with o = 3 and B = 3.44. Find the mean of the distribution.The lifetime of a semiconductor laser has a lognormal distribution, and it is known that the mean and standard deviation of lifetime are 9,364 and 15,671 hours, respectively. Determine the probability that a lifetime exceeds 10,172 hours. Suppose that X represents diameter measurements from a gamma distribution with a mean of 4.0 millimeters and a variance of 2.0 mm2. Find the parameter 1 The distance in miles between major cracks in a highway follows an exponential distribution with a mean of 8 miles. What is the probability that the distance until the next crack is between 13 and 20 miles
